238° Annals of the South African Museum. 
straight, forwardly directed medio-ventral spine, the spines becoming 
smaller posteriorly, on 7th segment nearly obsolete. Side-plate 1 
acutely produced forward in both sexes, 2 larger than 3. 
Pleon segment 3 with postero-inferior angle rounded quadrate. 
Telson as broad as long, with 2-3 setae in each subapical notch. 
First antenna longer than 2nd, 2nd joint a trifle longer and much 
more slender than Ist, 3rd half the 2nd, flagellum 12-jointed, accessory ~ 
flagellum equal to first 2 tlagellar joints, 3-jointed, 3rd joint very minute. 
Second antenna, gland-cone not very prominent, penultimate and 
ultimate joints subequal, flagellum a little shorter than ultimate 
joint, 5—6-jointed. 
Mouth-parts similar to those of L. kerqueleni Stebbing. 
First gnathopod in ¢@, 2nd joint stout, 5th setose on fore and hind 
margins, 6th equal to 5th (7.e., along anterior margin) and equally 
broad, oblong, palm a little oblique, with a stout spine at the defining 
angle and immediately distal to this a spiniform process, a small 
tooth near the hinge, hind-margin and especially the fore margin 
setose, finger curved, overlapping the spine, serrate on inner margin ; 
anterior margin of 5th and 6th joints with a number of small circular 
marks, from each of which arises a seta. In 2? not so stout, hind 
margin of 5th setose, 6th longer than 5th, oblong, palm transverse, 
convex, with a strong spine at defining angle, fore and hind margins 
sparsely setose. 
Second gnathopod in ¢ smaller than Ist gnathopod, 2nd joint 
nearly linear, the distal anterior apex produced as a recurved hook, 
5th more elongate than in Ist gnathopod, 6th equal to but narrower 
than 5th, narrow-oblong, very slightly tapering, palm transverse, with 
a small spine at defining angle, fore and hind margins of 5th and 6th 
setose, the setae on fore margin arising from little circular marks as 
in Ist gnathopod, finger overlapping palm, serrate on inner margin. 
In ¢ similar to ¢@, but 2nd joint without hook-hke projection, 5th 
shorter and broader proportionately than 6th, both joints apically 
setose on both margins, both not so strongly asin @. 
First and second peraeopods not specially setose, 2nd—4th joimts 
glandular. 
Third. to fifth peraeopods, 2nd joint oval, about twice as long as 
broad, 6th joint with 4-5 pairs of spines on anterior margin. 
First uropod, peduncle with stout apical spine, inner ramus longer 
than peduncle, outer ramus shorter, both with marginal and apical 
spines. 
Second uropod, rami a little longer than peduncle, outer ramus 
shorter than inner.
